In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details.

Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
According to an embodiment of the present invention, there is provided a hybrid cloud-based request forwarding method embodiment, it should be noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different from that here.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment provides a request forwarding method based on a hybrid cloud, which can be used for a terminal, where the terminal may be an intelligent device such as a smart phone, a smart watch, an ipad, a tablet computer, and the like, and the method is not limited in the present application.
Fig. 1 is a flowchart of a hybrid cloud-based request forwarding method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
and S1, acquiring the current load conditions of a plurality of servers in the multi-service cluster in the public cloud.
S2, determining a designated server according to the current load condition; the designated server comprises a first server which can provide the designated service and is determined according to the sequence of the current load condition from small to large.
When a client sends a large number of requests, each server in the public cloud has different configuration performance and different load capacity, and the requests are distributed according to the current load condition of each server, so that the individual servers are prevented from bearing excessive pressure.
And S3, sending the request information to the designated server.
S4, response information corresponding to the request information is received from the designated server.
S5, when the multi-service cluster in the public cloud does not comprise a server capable of providing the specified service, the server which is finally determined to be incapable of providing the specified service in the public cloud forwards the request information to the server in the private cloud; response information corresponding to the request information is received from a server in the private cloud.
The method includes the steps that a server capable of providing specified services is not included in a multi-service cluster in the public cloud, namely when the public cloud is abnormal, the abnormal conditions include the conditions that public cloud data exceeds a time limit, a request exceeds a public cloud limit order, the public cloud does not respond to data and the like, and the conditions that the public cloud hangs up due to human factors can be included. Due to the timeliness of data retained on the public cloud, a data overrun condition may occur. Data retained on the public cloud is also limited, so situations can arise where requests exceed public cloud restrictions and public cloud unresponsive data. At this time, the server which is finally determined to be unable to provide the specified service in the public cloud forwards the request information to the server in the private cloud, redirection of the public cloud to the private cloud is completed, and the private cloud completes the response.
Prior to step S2, the method further comprises: s10, acquiring the user account and the password carried in the request; and determining that the user account and the password accord with preset conditions. The request information is authenticated, if the user account number and the password meet the request of the preset condition, the authentication is passed, the request information is sent to the appointed server, and if not, the authentication is not passed. A request for authentication failure may be returned to the client.
Other authentication modes can be adopted, for example, a mode of using a client inside the system is used for assigning the unique id to the client, the permission token is set, the unique id is stacked into an encryption mode by jwt for matching, the matching is successfully passed through the authentication, and the request information after the authentication is passed is sent to the assigned server.
Fig. 2 is a flowchart of a hybrid cloud-based request forwarding method according to another embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
s100, establishing a server queue according to the sequence from small to large of the current load condition of each server in the multi-service cluster in the public cloud. That is, the priority of each server for receiving requests is determined, and the server with the smaller current load preferentially receives the requests.
S200, determining a first appointed server capable of providing appointed service in a server queue, and receiving request information sent by a client.
S300, generating response information according to the request information, and sending the response information to the client;
s400, when the servers in the multi-server cluster in the public cloud cannot provide the designated service, determining the server which cannot provide the designated service at last, and forwarding the request information to the server in the private cloud; so that the server in the private cloud provides response information corresponding to the request information.
Before step S200, the method further includes step S101, counting the number of requests received in a preset work period; reading a preset current limiting strategy for adding a current limiting label when the number of requests in a preset working period exceeds a preset request amount threshold; and extracting user information carried by the request, adding a current limiting label to the request according to a preset current limiting strategy and the user information, and designating the server to receive the request without the current limiting label. Namely, the request information is limited, and the individual server is prevented from bearing excessive pressure.
The preset work period is a reference value for determining the user request amount, specifically may be 10 seconds, 1 minute, or 3 minutes, and the preset work period may be set according to an average time used for processing the request by each server in the multiple servers.
The preset request amount threshold is used for judging whether current limitation is needed, and the preset request amount threshold can be set according to the maximum load amount of the request, namely the maximum processing request amount, of the server. When the request quantity exceeds a preset request quantity threshold value within preset time, judging that current limitation is required; and when the request quantity does not exceed the preset threshold value within the preset time, judging that the current limitation is not needed for the moment, and directly receiving the request information sent by the client by the appointed server. The preset current limiting strategy can be realized through a pre-written script file, and is used for adding a corresponding current limiting label for the received request according to the user information corresponding to the request, and then judging whether the current request is received or not through the current request corresponding to the current limiting label when the request reaches a specified server, and directly returning the request which does not meet the requirement to the client side.
The flow restriction tag is a tag for determining whether or not to receive a request, and specifies that the server does not receive a request including the flow restriction tag. Whether the requests need to be limited is judged by analyzing the user information, and then the current limiting labels are added to the different requests, relatively important requests in the requests can be identified through the user information, and the efficiency of server request processing in the public cloud is improved.
After the server in the public cloud adds the current limiting label to the corresponding request according to the pre-stored current limiting strategy, the request added with the label is directly returned to the client or distributed to other servers in the multi-service cluster in the public cloud, and the request without the current limiting label is directly received, so that the risk of server crash is greatly reduced.
The method for adding the current limiting label to the request according to the preset current limiting strategy and the user information specifically comprises the following steps:
and acquiring the requested user IP, judging whether the user IP is in the current limiting IP section, and adding a current limiting label for the request of the user IP in the current limiting IP section.
Other current limiting strategies can be adopted, for example, if the current is limited by a user group, a current limiting label is added to a request corresponding to a user in the current limiting user group, and a designated server receives the request without the current limiting label.
In this embodiment, a case where a server in a multi-server cluster in a public cloud cannot provide a specific service is called a public cloud exception, and includes: public cloud data overrun, requests overrun public cloud limit order and public cloud no-response data. But also public cloud hang-ups due to human factors, etc.
